Abstract (en)
The present invention provides a contact lens having novel myopia progression suppression capability, while enabling a good QOV to be obtained and ensuring myopia is kept from progressing. A contact lens (10) having a refractive correction power for correcting myopia and myopic astigmatism set in a central region (32) of an optical part (24), wherein a positive addition power in comparison with a power in the central region (32) is set in a peripheral region (34) of the optical part (24) so that progression of the myopia or myopic astigmatism is suppressed, a positioning means (46) is provided that specifies a circumferential position of the lens under a worn condition, and a lens optical axis (18) of the optical part (24) is set offset from a lens geometric center to align with a line of sight (16) of a human eye (14) under the worn condition produced by the positioning means (46).
